FEEDER.

Application filed January 3, 1925. Serial No. 405.

rlilhis invention relates to a feeding device, the general object of theinvention being to provide means for feeding a very small quantity ofmaterial from a receptacle containing the same so that this material canbe mixed with other material.

Another object of the invention is to pro vide means for regulating theamount of material fed by the device.

1U `While the invention is mainly designed for feeding bleachingmaterial to liour it will of course be understood that the apparatus canbe used for other purposes.

This invention also' consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, il lustrated in the accompanying drawingsand specifically pointed out in the appended claim.

In describing my invention in det-ail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which z- Figurel is an elevation of t-he improved apparatus.

Figure Q thereof.

Figure 3 is an enlarged sectional 'View through the drum or receptaclefor containing the material to be fed.

Figure l is a detail sectional view througl'i the drum.

Figure 5 is a view of one of the gates.

In these views, l indicates a supporting` member which has the bearings2 at its upper end for the horizontally arranged hollow shaft 3. Apulley 4 is Connected with one end of said shaft so that the same can berotated from any suitable source and a drum 5 is connected with theother end of the shaft. This drum is of substantially elliptical shapein vcross section and has a -circumferentially arranged rih G which hasgrooves 7 in its sides and perforations are formed in the drum and passthrough the center of said rib, these perforations permitting thematerial to pass from the is a longitudinal sectional view CIL drum intoa chute 8 which is supported by the extension 9 of the support l. Anopening lO is formed at the center of the outer side face of the drum sothat the material can he placed in the drum, this opening bemg closed bya cover 11. D

In order to insure the passage of the material through the smallperforations I place a presser foot l2 on an arm 13 which is secured toa shaft 14 by a set screw 15, said shaft passingthrough the hollow shaftis il and having its end bent twice at right angles and secured to aprojection 16 on the base or support l so that the shaft lilis heldagainst rotation. A spring 17 presses the enlarged end of the footagainst the perfo- G5 rated part of the drum so that this part 'of thefoot prevents clogging and insures the passage of the material throughthe perforations as the drum is being rotated. rlhe parts are so setthat the foot always engages that part of the drum which is lowerinostso that the material passing through the perforations will drop into thechute and thus pass to the point where it will mix with the othermaterial.

In order to regulate the amount of material fed from the drum I providea plurality of gates 18, each gate being' of channel shape so that itwill embrace the rib with its eX- tremities engaging the groove 7. Thusthe gates are slidably mounted on the rib and can be manually adjustedto cover or uncover the perforations so that a number ot' perforationscan be covered to cause the device to feed the correct amount ofmaterial.

lWith this invention a small amount ot' material is fed from the drinnand by moving the gates the amount of material can be varied to suitconditions.

It thought from the foregoing description that the advantages and novelfeatures of my invention will be readily apparent.

I desire it to be understood that I may make changes in the constructionand in the combination and arrangement of the G5 several parts, providedthat such Changes fall within the scope of the appended claim.

What I claim is A device of the character described comprising asupporting base, a hollow shaftthereon, an elliptical shaped drumattached to one end o1 the shaft and having a plurality ofercmnferentally arranged perforatons, a rib exending around the drum inalignment with the perforatlons, grooves on opposite sides of the rib,channel Shaped gates embracing the rib and movable n said grooves, Saidgates adapted to be manually moved over the rib to open and close sadperfor-ations, said gates being 'rotonally retained against accidentalmovement and a spring pressed foot Supported by the slla' havingengagement with the perforated part of the drum to assure of passagethrough the peror'ations.
